Tiers

Tiers are different worlds on the The Plague server, allowing new, progressively harder experiences on each Tier that you visit, and such are called Tiers to indicate the increase in difficulty.

Whenever someone logs onto the server, they are sent to Tier 1, and must travel the tier to complete challenges and quests to move on to the next tier, being Tier 2.

If someone wishes to travel to the next tier, then they must accomplish challenges, dungeons, and quests to get through to the next tier.

In-Game Behaviour
In each tier you progress, you unlock the ability to get better gear. For example, in Tier 1 you can only find leather armour and wood tools. This makes exploring a necessity.
