Collectus is a well-known NPC that can be found in the Frontier, more specifically at the tall pillar of terrain seen in Greenhorn Grove which is typically accessed via the 'Death Portal' in Rubble Spring.
Collectus is well-known for being the tutorial guide for new players that have recently joined Fantastic Frontier, as well as the quest-giver and the rewarder of the Collectus & The Itempedia Quests.
The name Collectus is simply a compound word of two words, 'collect' and 'us', referencing the collectibles that players need to collect in order to be rewarded by the NPC.
Depending on what the players have completed in their Itempedia, Collectus will reward the following rewards for certain sections that were completed by the players:
- Nature Master's Cape - rewarded if the player completed the harvestables section of the Itempedia
- Fish Master's Cape - rewarded if the player completed the fish section of the Itempedia
- Bird Master's Cape - rewarded if the player completed the feathers section of the Itempedia
- Monster Master's Cape - rewarded if the player completed the monster drops section of the Itempedia
- Collectus is considered to be an endgame quest giver despite being found at any point of the game. This is due to him giving the Fantastic Top Hat, one of the hardest items to acquire.
- The golden rabbit beside Collectus gives a slight reference to the white rabbit in Alice in Wonderland. Another reference is that a possible way to get to Collectus is through a hole in the ground, similar to how Alice jumped in a hole.
