UO: Renaissance
From UO Second Age
Ultima Online: Renaissance is the second expansion to Ultima Online. Its release was on May 4, 2000 and it marked the end of the second age area. The main change UO: Renaissance brought to UO, was the mirroring of the world and landmass, now known as Felucca and Trammel, while on Trammel PvP wasn't allowed anymore.
Of course the uosecondage.com server doesn't feature the Renaissance expansion, but the T2A (the Second Age) expansion only.
