Solculvis, a male, held the position of regent over the Mol'leaj system. His relationship with King Prana was marked by a persistent rivalry, fueled by their shared passion for amassing exotic and perilous creatures within their extensive zoos. Learning from his spies that Solculvis lacked any rathtars – the very beasts implicated in the notorious Trillia Massacre – Prana, determined to surpass his rival, engaged the services of smuggler Han Solo in an attempt to acquire rathtars, a mission that ultimately proved unsuccessful.
