Allusions

Allusions in Tibia are references to Real Life media, people, organizations, events, etc.

Amazon.com
In the Amazon Camp, there is a small room under one of the buildings. In this room is a mailbox and a large number of books. This is a fairly obvious reference to the large mail-order book distributer with the same name as the camp, "Amazon".com.

Pacman
In one of the Tombs near Ankrahmun, there is a hidden area that is an obvious replica of a level from the 1980 Namco game, Pacman. On this level, there are blueberries covering the floor tiles, with Oranges to represent the "power-pills" from the Pacman game. There are even a number of Ghosts on this level that will chase you.

Snow White and the Seven Dwarves
Deep in the mines under Kazordoon, there is a room with one Witch and seven Dwarf Guards. There is an Apple on a table, and behind a locked door is a bed - "You see a bed. There is a dark haired beauty sleeping there."

In the fairy tale Snow White, a princess hides with seven dwarves in order to save her life from the jealous queen. The queen eventually finds Snow White, and dresses up as an old woman to trick her into eating an apple. The apple is poisoned, and causes her to fall into a deep sleep.

Lord of the Rings
There are numerous references to The Lord of the Rings found throughout Tibia.

Frodo Baggins
In Thais, the name of NPC Frodo may have been taken from these books.

Samwise Gamgee
Also in Thais, the name of NPC Sam may have been taken from these books.

The Postman/Kevin Costner
At the Postal Service Headquarters is the NPC Kevin Postner. This appears to be a reference to the actor Kevin Costner, who starred in the film The Postman.

Vampires Don't Like Garlic
If you are wearing a Garlic Necklace when you talk to the npc Vladruc, he will act strange, and be reluctant to speak with you. In the most common mythologies about Vampires, they do not like garlic. In most accounts, garlic is not fatal to them but merely the odor of garlic can cause severe irritation to their skin, and direct contact can cause burns and have an "acid-like" affect.
