This server is a "reverse-engineered" version of the well-known (but offline for years now) PvP-Siege Server thedarkage.nl.
The most famous features are
Working catapults & cannons
Working drawbridges & drop gates
Many different classes to train all kinds of combat techniques
Conquerable flags
Lord of the Rings & Medieval Castle Maps
New classes with unique special skills
Maps specially developed for Siege PvP
pre 1.9 PvP combat system
For gamers from that time: We actually managed to dig out a few of the original maps from the early 2000s, but also built new exciting scenes to provide some variety. The best thing is to drop by to convince yourself of the new/old concept ^^
Peace.
