Solculvis was a male who was the regent of the Mol'leaj system. Solculvis had a long-standing feud with King Prana, as both collected dangerous and rare animals for their expansive zoos. When Prana's spies confirmed that Solculvis did not own any rathtars–creatures responsible for the infamous Trillia Massacre–the king sought to outdo Solculvis and hired the smuggler Han Solo to obtain rathtars for him, which ultimately went unfulfilled.
