Despite their massive size, Lacula Dragons are supremely stealthy creatures that rely on cunning wit to overcome the disadvantage of their large, flightless bodies. These dragons carve their homes into wet caves along the shores of sea cliffs, and use their resourcefulness to trap prey into the corners of large labyrinths of their own design. Typical prey often includes other dragons of medium size, but Lacula Dragons have been known to overcome larger creatures through sheer ambition and force of will. Their bite is often fatal to smaller creatures due to the potent venom in their hooked fangs, which is capable of paralyzing even the largest of adversaries. Although these dragons are solitary in nature and only meet for breeding purposes, a Lacula may be convinced to share its territory with another dragon if advantageous. In this case, the bonds a Lacula forms are everlasting, and any companions of a Lacula should count themselves lucky to have such a dragon willing to protect them.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Agendum's cave is just within Plumish city-state limits, and the government has decided that the issue is not worth pursuing if he doesn't attempt to expand territory. He seems nice and jolly, and he says humans aren't on the menu. He is a recent arrival, but he's quite old and probably well-known wherever he's from. Plumish denizens, for the most part, avoid Agendum and go about their affairs as usual, while travelers often try to find him to learn Cool Lacula Secrets or whatever. They often unwisely ignore the warnings from locals not to go into his cave. Agendum is surprisingly easy to find in there, and happy to talk. However, it doesn't take long for the explorers to realize that his secrets are just meandering tales whose purpose is to end in awful wordplay and of no use information-wise. He'll say to them, for example, that people who communicate by exchanging letters are experts on the topic of refrains in songs, and there's no escaping him and his words once he's started.
