How does Targon's Peak work, specifically regarding when it triggers and when runes are chosen and readied?

Ruling: Targon's Peak triggers when conquering and creates a delayed trigger that resolves at end of turn, at which point runes are chosen as targets and then readied.

Sequence:

• Targon's Peak triggers when conquering
• It enters the chain with no targets
• When it resolves, it creates a Delayed Trigger that will occur at the end of the turn
• At the end of the turn, the delayed trigger occurs and 0-2 runes are chosen as targets
• The trigger enters the chain
• Runes are readied on resolution
