This is where I'll put the background on the gang as it's revealed in Jackal and Rabbit.

ITEMS

Vial--Yassen drank out of this during the conflict at the inn and seemed to grow faster and stronger almost instantly. Little is known about this, except that the contents gave off a strange blue glow.

Stamp--Found by Wraith after defeating Yassen, this is a black box made of a curious material, with the bloodstained extrusion in the shape of a rabbit's foot inside.

Robes--The robes the gang wears seem to be sewn out of a special silk. In a fight with Koura, Yassen seemed to have some kind of force deflecting harmful attacks from his body.

YASSEN

Yassen is a blundering member of the gang who seems to be more concerned for his own safety and satisfaction than he is with doing the job right. His past mistakes have been punished with the shaving of his prized hair, leaving him bald until he earned back favor, although why he hasn't been considered a nuisance and killed off by now remains a mystery. His mistakes constantly endanger the secrecy of the gang, and it was a series of his mistakes that got Sabertache and company on their trail. Despite his carelessness, he is just as well trained in dagger use as any other assassin in the gang, and isn't a pushover in battle--Then again, nobody in the gang is a pushover.

Lerick

One of the apparent leaders in the gang, he has a no-nonsense attitude and doesn't participate in a lot of the more common activities, as he has sacrificed his stealth for strength. Because of his power and assertiveness, he is called in when things come to a fight and the cover has been blown, to make sure noone gets out alive with information on the gang's identity.

Common Gang Members

The term 'Common' is completely relative in this case, as the gang is actually relatively small. However, they are highly trained and formidable opponents in groups. There are several different kinds of recruits that are trained for their specific position; Recon, Retrieval, Guards, Assassins, and more that are yet to be revealed.

RECON

It's Recon's job to establish the location of the objective without being seen, and relay the information so that Retrieval can do their job. Because of this, Recon is trained to live in the shadows and kill swiftly and silently. Sheikah, obviously, are the choice recruits, although there are a few exceptionally skilled Recons from other races.

Level 5 Sheikah Thief

STR 2+5(Dagger)=7
3(Dual Wield)=5

AGI 3+3(Race)+2(Deku Agility)=8
INT 3
SPI 1 + 7(Robe)=8
SPL 11

Dual Wield level 2
Deku Agility level 2

RETRIEVAL

Once Recon secures the target, it's Retrievals job to, well, retrieve it. This could range from recovering a lost object, recovering a captured ally, or assisting in a battle. Because of this, they are trained to be both agile and well defended, so as to escape a battlefield unscathed with the object. This squad uses a broad range of races, although Hylians are favored for their ability to heal on the run. They are also trained to loot what they can within a short time.

Level 5 Hylian Mercenary

HP 45
STR 3+5(Sword/Dagger)=8
DEF 3+12(Armor)+1(Human Defense)=16
AGI 2+2(Deku Agility)=4
INT 1
SPI 1 + 7(Robe)=8
SPL 7

Human Defense Level 1
Deku Agility level 2
Disarm Level 1
Helm Splitter level 1

GUARDS

They are left to keep a perimeter around certain areas such as towns and safe houses, and are most equipped for battle. They are usually called in for backup in fights if they are in the area, although they take a considerably longer time to reach distant destinations compared to Recon or Retrieval.

ASSASSINS

These are the guys who carry out the assassination jobs, trained to make a kill quickly and loot the victim, leaving no evidence as to who did it, and usually no evidence that there was a murder at all. With the exception of Yassen, they all carry out their job flawlessly with great pride.
