If your old server is missing from the list, start with the period you played. Some names were reused in later eras, so follow both opening records and merger events. For the new USKO servers opening on November 12, 2026, see the new server guide.

Source / rights
Zion opened on SteamKO on December 8, 2022, when Hellsgarem, Cypher and Pathos merged. Sirius opened on January 22, 2019 with Altar and Vega and joined Dryads on February 23, 2023. Destan opened in 2012, Zero on December 8, 2022.
Why does Olympia follow two different paths?
The 2005 Olympia leads through Resurrection and the later Diez merger into the Oreads chain. The 2016 Olympia appears in the Rosetta–Minark merger instead. Searching only for “Olympia” can mix up those histories.
Looking into an old account
Use the server name, edition and year together. The merger path describes server history; use the relevant edition’s account and support screens to check which characters remain on your account.
What happened to characters in the server merges? 2023 merge rules
NTTGame ran all three 2023 merges under the same rules. Announcement and merge dates:
| Merged servers | New server | Announced | Merged |
|---|---|---|---|
| Rosetta, Olympia | Minark | January 11, 2023 | February 9, 2023 |
| Altar, Vega, Sirius | Dryads | January 26, 2023 | February 23, 2023 |
| Ares, Diez, Gordion | Oreads | February 9, 2023 | March 9, 2023 |
- Each account kept its 4 highest-level characters across the merging servers; the rest were deleted. Ties went to the character with more EXP, then to the older character.
- Your nation became the nation of your highest-level character. Characters with the same name got a rename option; whoever renames first keeps the name.
- Inn Hostess storage above 192 slots and 2 billion Noah was deleted. VIP Key durations were added together, and items over the VIP Vault capacity were deleted.
- Clans stayed; a clan was deleted if its leader's character was deleted or changed nation, and donated NP was refunded. Clans with the same name got a Clan Name Change Scroll, and alliance lists were reset.
- Nation treasuries, the Merchant Union Fund, kings and castle owners were reset.
- Account-bound mail was kept and character-bound mail (Draki rewards, for example) was deleted. Friend, chat block and market block lists were reset.
- Monthly NP and Draki rankings were reset, and Akara's Altar auctions stayed closed for the first 4 weeks.
- Unfinished skill, rebirth and other quests were deleted. A Cypher Ring not used before the merge became unusable. Badges and emblems carried over.
If an account had more than 4 characters before its merge, the lower-level ones were deleted that day. When you look into an old account, start by working out which 4 characters could have carried over.
