Overview
- Base Theme: Sunstone Fortress is a visual theme that can be applied to a player's Lair as part of the Lair System. The theme is based on Fortress of Solitude.
- The theme dictates the appearance of the base's Mainframe and Generator as well as the appearance of the player's Henchmen.
- There are 10 Amenitiy nodes in this base.
- After obtaining a theme, the Player must obtain a Deed which dictates the location of the Lair or Hideout in Gotham City, Metropolis or House of Legends.
- The theme is available as Sunstone Fortress Base from the marketplace. It has a complete new base layout which makes it unsuitable for PvP lair fights.
