Onward

Set in a fantastical world, where the populace once had magic, two teenage elf brothers, Ian and Barley Lightfoot, receive a wizard's staff as a prearranged gift from their father, who died before Ian was born and when Barley was too young to clearly remember him. The staff came with a spell that will bring him back for only 24 hours, so his sons can meet him. Prompted by Barley, Ian uses the spell, only to end up bringing back just his father's legs. This causes the brothers to go on a quest for a way to bring back the rest of their father before the time is up.
