How do you get the canoe in Final Fantasy 1?
When you visit Crescent Lake, there will be a group of men in the upper east side of the town called the Circle of Sages. Talk to them, they will give you a history lesson of the 4 fiends. The sage in the middle is called Lukahn. He is the sage from Cornelia whose prophecy gave the king and the people of Cornelia hope that Princess Sarah would one day be rescued. To the right of him is the sage who gives the 4 Warriors of Light the canoe they need in order to access Mount Gulg and the Ice Cave.
