Cytuj:
Q: I would like to know if any information about solving quests can be found ingame. Or is it Knightmare who wanted us to study Lord of the Rings trilogy to find any connection or inspiration that could be useful ingame?
Knightmare: I guess I'm supposed to reply to that by myself. To solve quests you are not expected to reference external sources. What is in the game can be solved by any Tibian with knowledge available on his or her world. References to other material are rather homages, allusions or just plainly poking fun. Ingame resources should be sufficient to solve all riddles. To find all the missing clues of a puzzle though, some ingame research and cross referencing might be necessary.
Q: I would like to ask if the information we can find in books can be futher expanded by talking to NPCs. For example, I would like to know more about "the 2nd earthen chamber", and I dont know if any npc would share his knowledge with me.
Knightmare: Some lore is of course expanded and referred to by NPCs. But not necessarily every issue mentioned in some sources is referenced in another. You have to understand though that neither people nor books - which are of course written by people - are 100% reliable. People have different opinions if not agendas which are reflected by what they tell you. The fun part is to evaluate information you receive, based on the reliability of your source in that matter. Some information is not cross referenced though. You will not find a book about any issue an NPC mentions and not everything contained in a book being expanded by NPCs.
Q: Does the item Excalibug exist ingame? Is it possible to obtain it? And what is the story behind it?
Knightmare: (laughs) With regard to the story there are multiple sources ingame, may it be books or NPCs. The excalibug concept already existed since some of the earliest incarnations of Tibia, and since then a lot of information, true and false, has been accumulated. It is up to you to decide what sources you trust and what the most likely truth for you is. That being said, you either believe in excalibug being obtainable, now or in the future, or not. Also it is up to you to decide how much effort you make in researching its lore and secrets.
