Delphine Temple

From LSWiki

Torches light this room, the holy place of Apollo, god of the sun. His devout followers come here to worship him. From time to time, he is even said to make a personal appearance. There are no walls. Instead, the room is defined by large pillars spaced closely together. A circular altar dominates the room, which smells strongly of the salty sea air. The area is brightly lit.

You can 'pray to Apollo' a few times and he will show himself.

This is Apollo, god of the sun and lord of light. He exudes a radiant beauty that outshines the light of the sun itself. He wears a toga of purest white, and a wreath of laurel leaves. A sense of inner peace radiates from him. He looks about nineteen dimins tall, five and nine tenths dimins wide and one and nine twentieths dimins long. He is in good shape and is giving off light. You find a weakness in Apollo's left foot.

If you wish to become one of the Apollonian Disciples, say 'Accept me as your disciple, great Apollo.' If afterward you wish to denounce your faith, say 'I denounce you, Apollo'.
