Ecology
Ancient Prismatic Dragon is one of the elder species, claiming a wide territory and shaping the ecology around it for centuries. It is most often found in underground regions. It is gargantuan-sized, which shapes how it hunts, hides, or fights. As a legendary creature, it is rare in the world and likely the only specimen of its kind in the local region.
Behaviour
Ancient Prismatic Dragon is intelligent, vain, long-memoried; it remembers slights for centuries and rewards loyalty in kind. Its Neutral alignment shapes how it engages with the world — predictable in tendency, even when unpredictable in detail. It is intelligent enough to plan, scheme, or remember. Spellcasting expands its repertoire well beyond what its physical stat block alone suggests.
Origin
Ancient Prismatic Dragon is introduced in Kobold Press's Tome of Beasts 3 (2022). Dragons in D&D canon trace to Bahamut and Tiamat, with each lineage having its own founding myth. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
