Agonlil is a Main Three island. It is the only island to be visited more than once in SMO&W and the only one besides Aectes to have such a variety of environments. Its largest areas are Lavaland and the Freezing Mountain Range. It also has a forest, a desert, and some shadowlands. It is the main setting of the only Dragons of the Islands book and the only major/main island to not appear in the Hippo Story Series.

The Land of the Ice Giants
The first SMO&W book took place on Agonlil. Sion (disguised as Commander Cion) sent Sammy out to capture Ice Giants Ki, Kai, and Seboan king Kaloro. Sammy, with the help of Muro, captures the Giants and King. Soon after Sammy leaves, Cion and Hrobrine arrive and scold Sion for not killing Sammy.
Lavaland- The Adventure
In the second Agonlil book, Sam and Muro discover the Seboan king Kuiri was angry with Odeskas for seemingly no reason. Sam and Muro set out, but during an EvilCreature attack Sammy slices a cave through Kuiri's mountain. At the end of the cave a Kocagotoon ambushes them. Unlike with the EvilCreature, Muro and Sam are unable to defeat it and get past. Then they find Kuiri, guarded by EvilCreatures, Kocagotoons, and Dracagonarious. Sam and Muro get past the guards and Kuiri lets himself get captured.
A Chrysophylax Story
Chrysophylax the Fire Dragon is on the Island attacking Lavaland. The No-Zicovus Fighting Group goes there on the Ocean Eye boat, but encounters Drolmp. They escape the snake by sticking a dagger up his head and destroying a volcano. They manage to defeat Chrysophylax and leave the island.
