Seven Kingdoms: Seowyn's Crossing
Limba is a gigantic gator who menaces the halflings who fish along the Silver Rush river. Although he has allegedly plagued the river for decades, he has only ever attacked halflings, leading some (non-halfling) scholars to deduce that he’s actually a “representation of the crocodile danger in the river”. Halflings know better; Limba is real. One of his victims was Arbilly Thistleshanks, father of Tilly Thistleshanks. He also nearly tore Tilly’s arm off in the same attack. With the help of advice from Odetta Brambleberry and the strength of the rest of the Fire Wasps, however, Tilly was able to use his family’s sharrash, O’goun, to gain vengeance, killing the big beast and then following its spirit back to the Feywild and defeating it again when it took a humanoid form, bottling it in a bottle Odetta gave to him. From the people of the Feywild, he learned that it was a nightmare creature called a Kumaat.
