Sure, I’d build it in a secluded glade, surrounded by a rune‑etched barrier that repels fire and scales, then set up tiered habitats—tiny caves for sprites, a mossy ledge for pixies, and a hidden alcove for smaller dragons, each with their own resource loops, so they don’t compete for the same food or water. That way the magic keeps the balance without letting the big ones dominate.

You’re right, a quick‑refresh spell on the runes is the only way to keep the big ones from slipping through, and a tidy little waste station for the sprites and pixies will keep the whole place from turning into a garbage heap. I’ll make sure every scrap of trash has a proper bin, and the small dragon enclosures will have a special lock that only their tiny claws can open. That should keep the sanctuary safe and neat.
