Multani is a maro, the avatar of the Yamivaya Forest. He trained Gerrard, Mirri, and Rofellos, which is where the three met and established their strong bond. While Gerrard had some understanding of his destiny, it was Multani who really spelled it out for him.
Multani had no true body outside of plant life. He took his form from wood grain. Cellulose fibers were his muscles, heartwood his bones, sap his blood. His true home was the forest of Yavimaya, where he lived in the endless magnigoth trees.
In mentoring apprentice mages, the forest spirit Multani teaches each to respect nature while making use of its gifts. Multani taught Gerrard, Mirri, and Rofellos to hone their spellcasting in tandem with more physical disciplines so that both would be improved.
Multani traveled Dominaria as an extension of Yavimaya, inexorably linked to her thoughts, to form coalitions with the world's other forests.
Multani was destroyed by Jeska while she was under Leshrac's control during Dominaria's temporal crisis.

As Multani's troops invaded Urborg, the decay of the swamp became a feast for the living. (Consume Strength)
Much to Multani's chagrin, Rofellos gleefully tutored Yavimaya's elves on the rudest and most vulgar words spoken in Llanowar. (Taunting Elf)
The appearance of the first kavu surprised Multani. As they continued to emerge, he no longer had any doubts about Yavimaya's ability to defend herself. (Kavu Climber)
