Description

East Isles has opened as a test, play it here https://www.roblox.com/games/8118775974/East-Isles-OPEN-TESTING. Since roblox decided it would do saving errors we've had to start from scratch however, so this is only Build 1 of the new Slenryth Isles project. Build 2 coming soon with remade (again) and revamped engines

Membership history

Growth

4 measurements spanning 56 days, net +4. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 636–642 and does not start at zero.
