The Idian Depths, also known as Katalam UndergroundKR/EU was a large underground cavern system that served as the game's primary endgame PvPvE region between patches 4.0 and 4.8. It was introduced as the third and final new area of the 4.0 update, and was open to players of level 65 and above.
For much of the 4.0 update the Idian Depths contained the entrances for virtually all of the (at the time) endgame instances, and also offered readily available amounts of the highly valuable through a variety of quests. Bosses and named monsters on the map could be hunted for additional rewards, such as gear. All these factors made it a hotly contested and active location, both for PvE and PvP purposes.
In later patches most of the instances on this map were relocated to other maps, and with becoming rapidly more available through other means the role of and activity on this map was greatly diminished. In the 4.8 update this area was recycled into an optional PvE farming area for level 65+ characters, but any valuable drops were removed shortly after bots had begun to flood the region. Since then the area mostly lied abandoned. In the 5.6 update the few remaining NPCs were also removed, and in the 6.0 update the region was removed altogether.
The Idian Depths are considered to be a great place to extract Ide thanks to bountiful Idium mines within. Originally, this place was intended to be an emergency shelter for the Danuar in preparation for the event where Tiamat's forces would gain complete control over Katalam and Danaria during the invasion. The few Danuar who had survived the onslaught evacuated here, but before long they fell to a destructive malfunction in one of their weapons, leaving the place unattended.
Tiamat eventually made her way to the Idian Depths and discovered the ancient weapons left behind by the Danuar, prompting her to research how to use and replicate them. Her aspirations fell short when Beritra betrayed her to gain control of this secret research and left her to die in Tiamaranta. After Tiamat's death, the remnants of her armies which had scattered across Katalam came down to Idian Depths to avoid the attacks from the Daevas and Beritra's forces. From here, they divided into two opposing factions: those who dreamt of a glorious comeback and those who made a pledge of loyalty to Beritra.
During the Upheaval the Daevas, fearing a collapse of the structure, fled out to seek protection from Beritra's invasion, only leaving Shugos behind. As the disaster's chaos settled down, Daevas discovered the Idian Depths mostly intact. They created secret portals in the remaining regions to access it at will. Although mostly the same, the only presence from their opposing faction were the leftover banners on the walls.
- Via access portals found in various locations across Katalam and Danaria.
- Via the Shugo Teleporter in Danaria.
- (Post-4.8) Via Idian Depth Corridors that appear in any of the set spawn locations in Levinshor, Kaldor, Cygnea/ Enshar. Their spawn locations can be found here (look for the red rift icon on said maps), and they may appear in one or multiple locations at either 12pm or 12am server time on Mondays, Wednesdays, Thursdays and Fridays.
Lay of the Land Edit
Once the last stand of the Danuar, this underground cavern system is littered with ruins and other relics haunted by the ghosts of the ancient race. The remnants of Tiamat's forces have taken up residence in some of the areas, while Beritra's legions have arrived here in their search of . Meanwhile, the Elyos Guardian Detachment, Asmodian Archon Battlegroup and Shugo Commerce Union have also ventured into the Idian Depths in search of new opportunities, profits, knowledge and anything else that could allow them to gain the upper hand.
Segarunerk's Bazaar served as the neutral ground and base of operations for both races. The town was split into two halves, with the Asmodian NPCs & Elyos obelisk being located in the left half and the Elyos NPCs & Asmodian obelisk in the right half. Shugos offering ranging services were found in both halves, but most would only accept as a currency. Players would need to cross between the two halves frequently, so it was advised to stay near the Shugo Guard NPC patrolling the connecting corridor (contested area) in order to prevent being picked out.
Idian Depths was the main PvPvE area of 4.0 and a great place to both farm for kinah and PvP. There used to be daily quests for and Manastone Bundles, and the monsters could drop anything ranging from ancient manastones to the materials needed to craft , along with other valuable drops. There were several legendary and ultimate grade boss monsters that could be hunted in groups or alliances for rare gear or exclusive skins. A Shugo NPC would randomly spawn at one out of four possible locations at times, and allow players to trade in any obsolete AP or gear pieces in return for AP, at the best possible rates in the game.
Post-Upheaval (4.8+) Edit
With the 4.8 update this area was transformed into a farming area for players to slay monsters for drops. All special merchants, like the Ancient Coin traders and faction-specific NPCs were moved to other areas, leaving only basic NPCs such as the Soul Healers, General Goods Merchants, Trade Brokers and Warehouse NPCs behind. Named bosses were also removed from the map, leaving behind only generic monsters for players to kill. Unlike its predecessor, each faction uses its own 'copy' of this map after 4.8, meaning there is no way to meet the enemy faction inside.Drops in this area may vary from to common ancient manastones, but are mostly junk.The most desired item was the , a special item that had a small chance to drop from any monster on the map and could be sold to a vendor for 100 million kinah. This item was secretly removed from drop tables in both regions in a later patch, supposedly to combat gold sellers and bots which had begun to overrun the region.
Currently not accessible from here, the entrances to these dungeons have been moved to other areas throughout later patches
