Things have been slow lately. I haven't finished as many requests as I wanted so far. Really Sorry for making you wait so long for those guys. I don't like to draw a full pic unless I can go full out on it. I don't want a "sketch dump" quality to be giving to a request. Guess it's the anxiety of my impending exams. Makes me feel sick, kinda like that sinking feeling you get right before a drop at a roller coaster, or if you're anything like me, when you jump from a really high place in a video game. Well, time to talk about the pic I guess...

Kinda hard making Valekins look different. The Io "twins" are "Twins" Due to hatching from the same egg. Nax and Dax have very separate concept of "Order". Dax is a hero, a walking symbol of Justice, and Law. Dax is by the book, and prefers to bring criminals in alive to face justice for their crimes. One can consider him a Paladin.
On the other claw...
Nax lived a different path. While his brother was a shining beacon of light, Nax was the "lesser known" brother. A walking shadow, Nax's art in stealth was his gift. Unseen, unheard, Nax worked his way up the assassin ladder. Becoming more than familiar with the underground scums of society. Without anyone knowing of his ironic relation with his brother. Taking contract after contract, until only the highest bidder could afford his "services". Until one day, He got a contract to end his own brother, and then another, and another... The underground wanted Dax dead, and he who got his head will have a fortune unimagined. Nax was secretly livid. No one, No ONE shall lay a hand or claw on his own blood. Nax "Accepted" the contracts, and triggered, what is now known as "the Purge". With the secret, silent help of Nax, Dax managed to bring justice on an alarming number of criminals, and who ever Dax could not touch, Nax finished off up close and personnel.
With no one left to pay for Dax's head, the contracts where voided. The underground never fully recovered from that event.
Nax never changed his ways. His nature was subterfuge and murder. For Dax he was the last "Big player" of the underground.
Dax needed to bring in Nax for his own crimes of assassination. The two where caught in a awkward situation. If Dax refuses to bring in his own brother than he would be violating his alignment but then Nax will be executed, and if Nax returns back to his old life, then the underground will know for sure who is responsible for "The Purge". Nax will be seen as a Traitor by the underground and forever live a haunted life.
It was at this time [redacted] was founding the Vale Empire. [Redacted] postponed this dilemma, He new of the two's talents. Dax's ability to rally troops into following him through hell and back, and Nax's skills at subterfuge. [Redacted] Employed the two as his vassals. To cut a story short, They two survived the conquest of the Void. But the old dilemma returned, but now there was a solution. [Redacted] needed some one to watch over the citizens of the new empire. To protect everyone from any force of evil that wishes to ruin and stain the Emperium. [Redacted] Knew of Dax's history and was perfect to become the symbol of justice, but [Redacted] Saw a way for Nax to "clear" himself of his past misdeeds as a hired assassin. Nax will become Just like his brother in every way, but as a shadow. An Unseen guardian, Just like how Nax defended and aided his brother when he was haunted, Nax will remain in the shadows aiding his brother unseen. Dax will bring justice to all who break the law, and Nax will bring justice to those the Law forbids Justice to touch. No one will be above the hammer of Justice for those who think they are above the Hammer will be cut down by the Dagger. Dax became Leader of the Town Guard, and Nax became leader of the Secret Guard (Secreat Police). Known simply as "•". With Guards and Assassins of •, no true crime lord can ever hope to come into power unchecked. For Dax controls the streets, and Nax controls the underground. Do not think any "banned" Goods can be sold within the empire without Nax knowing about it and getting his fair share of the cut. After all... even the black market needs to be taxed...
