Heartseeker Dragons are very social creatures that emanate a sweet chocolatey scent. Their captivating perfume easily attracts adult dragons that don’t yet have a mate. Heartseekers use their keen sense of smell to detect solitary dragons and potential mates in the area. By rubbing their fins against objects such as trees and rocks, they leave a scent trail for the other dragons to follow to meet each other. Although these dragons are seen year-round, the scent of a Heartseeker becomes particularly potent during the middle of winter. During this time, a single Heartseeker may play matchmaker to dozens of dragons, but he will also choose a special mate of his own.

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.

Opel's treasure is neatly arranged, its quality of care rivaling or exceeding most private curiosity cabinets. He collects minerals and ores, from plajioklayce to nefeline to grosulre, along with plenty of well-known specimens such as safeire, tolc, and ubsideine. Unsurprisingly, his favorites are the opels, his namesake, of which he has over 30 pieces sitting in the highest tier. One will soon notice that Opel's spelling and capitalization are abysmal, and he refuses to fix them. That's why he was never allowed to appraise gems outside his property. Even labeling for similar minerals often don't agree on a single spelling: one label for a pebble of agate says "syklopss ahgeit", while another's says "latis aggaite". Some people feel that Opel does this on purpose to be annoying or something. Intentional or not, the writing is confusing and uninformative, and the mineralogy enthusiasts feel Opel's insistence to do all of the collection's labeling himself is a waste of a good museum.
