Hey it´s been a while since I used you, Sepulcher.
Saga of Gustavo begins with the mention of the gods´ feast on Ostara to celebrate the spring equinox. The feast on Ostara takes place in Asgard, reimagined here as a heavenly palace.
I don’t have time for that, and the World Tree is not in this realm--
Now go off and train under the Yggdrasil the World Tree for a year!
After Gustavo is banished to Midgard (Earth) he arrived to the island Lofoten (where Gustavo retrieves his axe, Sepulchen), then to Lundr, a small town of Vikings. The Vikings think the demigod is there to help save their town and Gustavo went with the idea to protect the village and defeat a villain, so maybe he can be welcomed back to Asgard.
Gustavo journeyed to the small town of Klif ready to use his axe, Sepulcher, and ran straight into Klif. Klif was in ruins, covered in ash and soot, caused the villain Fenrir.
Gustavo was stopped by a supernatural force to find Sleipnir, the eight legged horse in the Evergreen Forest. After five days, Gustavo arrived at the forest and finds Sleipnir. Sleipnir tells Gustavo to train under the Yggdrasil, or the World Tree.
*Yggdrasil, the World Tree appears*
Gustavo returns to Klif and confronts Fenrir. Fenrir sent his serpent, Jormungandr, to kill Gustavo. Gustavo tried to use Sepulcher (his axe) but to no avail. Gustavo was bitten by the serpent in the ankle and laid there in pain. Being a demigod, he quickly healed and acted quick duplicating caves and tunnels to confuse Fenrir. Gustavo defeats both Fenrir and his snake.
The people of Klif hold a 7-day parade to commemorate the hero who saved their town from Fenrir, blue decorations are everywhere. Gustavo is welcomed back to Asgard.
