Someone who hands you the map after burning their own to learn it.

means A trusted, experienced person who guides, advises, and helps develop someone less experienced.

from From Homer's Odyssey: Mentor was the trusted friend Odysseus left in charge of his household and his son Telemachus when he sailed for Troy. The goddess Athena often took Mentor's form to counsel Telemachus, so the name came to mean a wise guide. It entered wider English use partly through Fénelon's hugely popular 18th-century novel Les Aventures de Télémaque, which made Mentor famous all over again.
