Quorlu

Quorlus are multi-limbed, silicon-based beings who burrow settlement warrens in their tectonically active world. Quorlu physiology runs hot, like their planet, but they’re calm and value connection and new experiences. Their home world is Quorlosh in The Vast, a geologically active planet with a thin atmosphere.
Society
Quorlus live underground in the stony crust of Quorlosh, where they delve for and farm minerals which they eat. Due to the instability of their habitat, quorlus are resilient to loss and accepting of impermanence. When a quorlu settlement is damaged, they simply dig out and repair, and avoid rebuilding where subsequent destruction is likely.
Despite their abundant raw wealth (by other races' standards) and toughness in combat, quorlus are peaceful and value experiences, and few truly enjoy fighting. Their military traditions, which come from their engineering customs, emphasize explosives. Quorlu voices are considered to be soothing by many other intelligent races, especially when singing, which quorlus love to do. They speak a highly tonal, trilling language which is very hard for other races to master, and includes delicate vibrations that sound especially pleasant to Shirrens due to their sensitivity.
In the Pact Worlds
Quorlus have a diplomatic mission and enclave in Absalom Station. Some of them work as explorers in the Starfinder Society or as prospectors in The Diaspora or on inhospitable worlds, where they are willing to take on jobs dangerous for carbon-based life.
