Royal Resident

The Royal Resident is an NPC located in the Barracks of Heroes at. 57 dialogue lines in, it teleports to (on top of bed). At line 79 it transforms into a cow, and at line 94 into a sheep, followed by revealing that he has no name at line 130. 21 lines after becoming "No Name", the NPC gives the player a special item called The Cake as a reference to the game Portal.

In an attempt to make you leave his room, the NPC will begin counting down from 5000 all the way to 0. If the use/interact key(default right-click) is held down on the NPC, it will produce a new number approximately every 5 seconds, which means it will take roughly 25,000 seconds, or 416.7 minutes, or 6.944 hours to complete the countdown.

Upon completion, the NPC will stop talking, and the player will receive the Royal Conversation achievement.
