Interlude is the most popular Lineage 2 chronicle on private servers: the final Chronicle 6 update, before Kamael, with a well-known class balance, Olympiad, Seven Signs and castle sieges that players still know by heart.
High-rate Interlude (x101+) skips the grind: characters are ready in hours, often with custom zones, auto-farm or GM shops. The game is mass PvP, TvT events, Olympiad and sieges from the very first weekend.
Interlude servers in this rate range right now: 9, 1 of them opening soon. VIP projects come first, then servers are ranked by player votes this month.
