They do sound like very good ideas. I'd love to see them in the mod tbhHmm.
Just a few ideas, not sure if they're good or not.
- Revamped Ultrablivion would be nice, with new attacks, AI, etc., to make him more unique.
- A new sword shrine. If that's possible, with Eon's Eternity (something like Aeon's Eternity) or something like it inside.
- A dragon's den biome. Preferably with Dragonlings, Dragon Eggs (could hatch if the player is within a certain distance of them), and Arch Dragons, etc.
