Hello Tibiantis community.

Yesterday I've been walking on Darama sands and I fell into a hole with two black slimes, called tars. Managed to fight them and then I figured out that in the corner there was already an adventurer who probably also fell into the hole but some time ago (they were dead), because what I've found inside was an broken sword, mouldy cheese, worn pair of leather boots and a badge. Then I read the badge and it was written: special agent Cox, TBI.

So I went to the TBI Headquarters to meet TBI Captain, Chester Kahs. I reported to him what I've just found and then described circumstances where the body was. Reward was 1k and some informations, Chester Kahs said:
- Cox was exploring Zone XV
- Cox died during exploring Zone XV
- Chester Kahs asked Cox to stop exploring Zone XV (at least they said so)
- Zone XV is synonym to describe Ankrahmun
- TBI captain asked me to forget what I figured out and said that Agent Cox died by fishing or fallen asleep and drowned during high tide.

Then I went to Darashia to ask citizens about Ankrahmun and:
- Ankrahmun was a beautiful city in the times of Banor (grand warrior, legendary founder of Ankrahmun)
- Ankrahmun is now full of bandits, undeads and evil creatures. Abbas is the one who guards Darashia against bandits and undeads. Definitely not safe.
- No one in Darashia seems to know of what Agent Cox was doing
- There are notes in Ankrahmun ruins excavation site that the place was visited by a warlock from demona accompanied by an Efreet general authorised by Malor (king of efreets) to discover weird magic activities in Ankrahmun (they discovered some kind of "tar aqueduct", which might be used to get inside "the mysterious structures" and they were thinking of drain the pipe system - to get inside)
- There is also a book which describes that once in a while green djinns invaded Ankrahmun and Banor managed to defend the city

What I am willing to try:
- get to know what TBI Agent, Cox was up to (about what he did know, what he discovered)
- continue work of TBI Agent Cox

So what I think what might be possible:
- somehow join TBI and ask Chester Kahs for help if it comes to discover ZONE XV or get mission from them to help them actually
- ask NPCs what they know about Ankrahmun, TBI, Agent Cox, the fall of Ankrahmun, how to drain the pipe full of goo

Any thoughts and ideas would be very welcome.
