How do I get new dragons in Dragonfire?

A dragon hatches as soon as you gather 15 of its Relics. To get new dragons:

• Hatchery Chests: the main route. With the Pity System you're guaranteed an Epic drop every 130 pulls and a Legendary every 250 pulls.
• The Conqueror's Chest: Epic/Legendary Relics only (reward 1 = 75% Epic / 25% Legendary).
• The Market: buy a targeted dragon's Relics directly with shards.
• Special rewards: for instance Vaeldra (Epic), granted for linking your HBO Max account, and Dawnseeker via pre-registration.

Strategy: concentrate your pulls and your shards on one dragon at a time so you cross the 15-Relic threshold fast, instead of scattering.
