Lagomus

Lagomus look very similar to normal rabbits. They have four legs, though they are designed less for speed and more for digging. This includes a large pair of digging claws on their front, similar to a badger. They also share the rabbit's large ears, which are generally up in the air, though can lay flat against their back while they are underground. They also have large front teeth like rabbits, designed to scrape the blue lichen they feed on off rocks. Their fur is very soft, with a blue hue coming from their diet.

Lagomus evolved in a very alien environment, where the atmosphere was a dozen feet high and the land is dry. There is water on the moon, though it is much sparser than on Savinaru. The Lagomus are low on the moon's food chain, leading to a burrowing lifestyle. They dig in the lunar soils, forming burrows much like their terrestrial counterparts, coming out to graze on the lichen that covers much of Elamsha. They always have their ears up for predators however. They are predated by a small species of wolf, which is still bigger than them. They also have to contend with other lunar beasts, such as frogs who have taken over the crocodile's ambusher niche and terrestrial crabs that wander around scavenging. While the lunar ecosystem is less diverse than Savinaru's, the same laws of nature apply to this miniature ecosystem.

When people heard there were cute little creatures on the moon, there was a push by the wealthiest of society to try and have one as a pet. Show off their status by having a beast from the moon in their home. While a handful of species were brought back, the lagomus were the most popular, being deemed the cutest of the bunch. The first few lagomus brought back died from the dense and rich atmosphere before people realized what was happening, leading to specialized enclosures for these exotic pets. However, thanks to breeding efforts with terrestrial rabbits, a hybrid was created that retained most of the lagomus appearance while having a physiology capable of surviving on Savinaru. This allowed people to have a lagomus as a pet without building an expensive custom environment so their pet didn't collapse. For a time, they remained the purview of the rich, though as these hybrids continued living and breeding a few inevitable escaped. While they were unprepared for the giants of the wilds and so very few exist out there, other classes managed to capture them and eventually they spread across dozens of cultures as pets.

Lagomus possess a weak form of tremorsense, that gives them the ability to detect surrounding creatures through vibrations the ground. This sense works best when the lagomus is huddled in a burrow, though it sometimes give an early warning when out on the surface. Their large ears also give them excellent hearing, which is their main sense for detecting danger.
