Ska Bloodtail

"Ska felt his musk glands try to clench but he fought down the urge with a hissed breath and a shudder. He rose to his full height, feeling almost as massive in his gromril armour. He took his axe in two paws and stared down the oncoming orc. The orc broke into a run, leaving the lesser green-things behind him and driving tiny cracks into the long-suffering stones. Ska tried to ignore the vibrations trembling through his footpaws. He was Ska Bloodtail. He would win."

—Ska Bloodtail, lieutenant of the Red Guard & right paw of Queek Headtaker.

Ska Bloodtail of clan mors is the right paw of Queek Headtaker and the lieutenant of Queek’s elite, The Red Guard. He is referenced as dimwitted, brutish and stupid. However he is capable, loyal and fearless by skaven standards. Although his unmatched loyalty is by far his most defining feature, he has stood unflinching before one of the chosen of the horned rat, the grey seer Razzel to protect Queek from malicious magic. Ska has taken a dagger in the heart to save queek from a clan Rictus ambush led by Toskitt, without thinking of his own wellbeing. And shoved his warlord out of cave inns, consequently exposing himself to the rubble. More imporant yet, he is still alive to protect his superior. He is what every skaven wants in a lackey, but sorely lacks. Despite this Ska Bloodtail is probably the only skaven, inn the entirety of the under-empire that has the strength of arm to commands Queek's respect, the loyalty to ensure his trust and meakness to survive in his position as the underling of Queek Headtaker.

Lieutenant of the Red Guard
"Ska fidgeted nervously. He threw frightened glances around the grim section of tunnel but any faint hope of a friendly face was soon exstinguished. Those traitorious vermin, he thought. They had always been jealous of him."

— Ska Bloodtail reffering to his fellow Lieutenants when confronted by Queek about the whereabouts of Grey seer Razzel.

Ska is a fairly influential skaven since he earned the trust of Queek, which is a powerful diplomatic tool and useful for intimidation. Although he is frightening in his own right without the threat of the Headtaker, he is sturdy, strong and unusually large,even for a stormvermin, standing almost as tall as a human. Despite his own glories and feats, Ska Bloodtail is most known for being Queek's lackey. Ska is always where Queek is, with a ready clawpack of Red Guard at his disposal. With more than his share of battlefield expertise and many scars to show for it, Ska is also responsible for all military matters Queek should be doing as warlord, such as recruiting troops and administering the army. In addition to this he also relays and enforces Queeks orders.

The first recorded major battle where Ska took part, was when Queek Headtaker & Sleek Sharpwit led an army to destroy the weaponry and forges of Karak Azul, he was present during the battle as part of queeks honorguard. In addition to this, when Queek led his army to battle the greenskins of black crag, Ska Bloodtail was tasked with making sure the grey seer Razzel died. During the hectic battle, He eventually had to give up on the frightened grey seer and engage the enemy with his stormvermin, if only to anchor the line long enough for Queek to retrieve King Kazador's kin. And during the final assault on karak eight peaks, together with Queek Headtaker and his Red Guard, Ska fought King Belegars hammerers to seize victory. Ska Bloodtail was more than a match for even the kings seasoned bodyguards.

Already a seasoned veteran in his own right, Ska showed his resolve during the last battle against Skarsnik's greenskins. The nightgoblin warlord had black orcs from the darklands to overpower the skaven, however Queek promised breeding rights to the three of his Red Guard who killed the most black orcs. This proved sufficient to incite the stormvermin to new heights of courage, and Ska once again was more then up to the task. He wrestled with the unatural strength of the orcs, using his own massive bulk to match the brutality of his adversaries. After Queek had eviscerated their leader, he ordered Ska to kill their standardbearer and seize victory.

"Ska! Break them! called Queek, cutting down two more of the black orcs. Ska nodded, slammed a black orc out of the way, and leap at their standardbearer. The black orcs' metal icon wobbled in the air as ska attacked, then fell.
