Oscar's lessons with the lizardfolk were enough for him to learn of a new form: the giant toad. He put that to good use fighting Baern and Toil, and now he has returned to Yenelas City once again. The gricks continued to grow while he was gone. They now seem large enough that they could bear a smaller person, halfling or kobold-sized, but they will need more time before they are ready to hold even a half-elf built as lean as Oscar. He now has some more downtime in the city, with which to pursue his own interests.
