Realms

In HyperRogue there are several realms to explore, each with different monsters and environments. Each realm has a treasure the player must collect. Collecting at least 10 of the treasure will unlock the Orb specific to that realm and in the Crossroads. Collecting 25 or more of the treasure will unlock it in all realms, except where the game has specifically excluded it because it would be too unbalancing or overpowered. However, the more treasure is collected, the more monsters will spawn, which makes the realm increasingly dangerous. Some realms may have secondary orbs that may appear as well.

In classical adventure mode, the player always starts in the Icy Land. Occasionally a Great Wall will appear, marking the border with another realm. At the start of the game only a small number of realms are available. As the player collects more treasure and defeats more monsters, more realms will begin to appear. Some realms have specific requirements of how many of a certain type of treasure must be collected before it will appear.
