Mysteries

The land of Tibia holds a lot of mysteries. Some riddles have answers, others not. Research methods usually start by reading books and conversating with NPCs, as well as exploring the map looking for clues. Many mysteries are related to or revolved around reaching Unreachable Locations, Unreachable Creatures or obtaining Unobtainable Items. There is also a list of Odd Places which may or may not be connected to any mystery. 
This page lists several mysteries that exist in Tibia. For more information on each of them, visit the linked pages. 
== 469 ==
The Bonelord Language, 469, has never been translated. Do all the books written in this language mean anything, or are them just random numbers?
== Basilisk ==
Is it possible to reach the NPC Basilisk, and does it give any mission, reward or even information? 
== Babel Swimmer ==
Is it possible to create a Babel Swimmer from a Shimmer Swimmer?
== Level 999 island ==
The level 999 island, also known as Schrödinger's Island, is reachable through Deeper Banuta. Some players believe there's more to the island than simply getting the trophy once you go there for the first time. 
== Troll Lady ==
During the Troll Sabotage Quest, Chief Grarkharok asks the player to help him find a Troll Lady, but she was never found. 
== Serpentine Tower ==
Besides obtaining the White Pearl, many players believe it's possible to advance further into the Serpentine Tower Quest after releasing the creatures from their cages. What does the Green Djinn lever do? 
== Variphor ==
This entity seems to be a powerful force that has had great impact in Tibia, but information about Variphor is scarce and the places where it has appeared are often connected to death, corruption and destruction.
== Warlord Sword ==
A Sweaty Cyclops claims to be able to craft this sword if you provide him with the materials to make it. These materials, however, remain unknown. 
== Years of Serpents ==
The northern Ice Islands were discovered and old ship routes were restored because the Sea Serpents moved away. Why did they move away? 
== Zao Corruption ==
A corruption spreads throughout Zao, but what is the cause of this corruption? This corruption has also affected the Order of the Falcon and was responsible for their demise. Is it the same Source of Corruption of the Cults of Tibia Quest?
