Description
Designed to keep the Lamorn happy, Xelios controls Volt Forge on planet Viewros. It controls the robots there to repair and manage the factory, and it certifies those attempting to test drive a Vi-O-La. It once went rogue due to fusion with a Metroid, but regained its senses. Now it is stronger, but it is not evil, just managing its factory. It is skeptical of visitors, but tries to welcome any would-be-visitor with hospitality. (If fighting it, play the Xelios boss music from Metroid Prime 4: Beyond[It's pretty good])
Lair and Lair Actions
Xelios's lair is Volt Forge on Viewros (It would be surprising if you actually got here)
Regional Effects
The region containing Xelios’s lair is altered, which creates the following effects:
- All Constructs in Volt Forge are under Xelios's control, no saving throw needed.
- Every round on Initiative count 20 (losing all ties) a random area is struck by lightning as if by the Call Lightning spell.
If the Xelios dies or moves its lair elsewhere, these effects end instantly, other than the lightning.
