Why is he so far from the Kingdom

The white-robed elf helped Oliver and gave him a healing potion. They were vigilant of the sudden arrivals but after Oliver regained consciousness he instantly apologized and politely sought help.

He didn't ask for much and just borrowed a communication device for a while to contact the Academy. Oliver was gland they landed in a place filled with life instead of a dangerous forest or worse a desert. In their current condition, there was no way the kids would survive without proper rest.

While Oliver was busy contacting the Academy. An old elf grandma took the kids into her wooden house.

The girls were relieved when they took a warm bath and changed into better clothes provided by the kind grandma. Well, the clothes were basically large white robes but the robes were a hundred times better than their blood-filled clothes.

The boys went to a separate place to bathe and change their clothes. After they were clean the old grandma gave them warm food.
