|From the Edda|
Heiðrún grazed the foliage of the Lerad (Læraðr) tree, which also grew on the roof of Valhalla. From there, her udder would produce and fill a giant cauldron full of mead every day, served by the valkyrie to quench the thirsts of all the warrior spirit inhabitants, einherjar.
Odin, fearing food poisoning from the enemy, abstained from eating, taking in any and all nourishment from Heiðrún's mead instead. One can dictate that the faith bestowed in this blessed goat by Odin would herald an aura of being "trustworthy".
Heidrun appears to have had a reputation for being sexually promiscuous. In an acerbic exchange between the goddess Freyja and giantess Hyndla (lit. She dog, Bitch) in the Edda Hyndlujód, Hyndla compares Freyja to the goat:
Turn away from here! I desire to sleep,
You ran up to Ód ever howling,
One author goes so far as to describe her as "lascivious," which, it must be admitted, is a rather unusual adjective for a goat — but a great one for the unofficial mascot of a den of sin and iniquity such as this.
