Chapter master Astovadion Cestanen the “Iron Shield” hero of Vernistior Astovadion Cestanen is the current chapter master of the Shields he is a legendary hero who holds the chapters relic which is “the Shield of Manus” which is said to be forged by ferrus manus himself. Originally Astovadion is from their home world of vernistior IV and was inducted at an extremely young age he was only six before he was even old enough to become a marine. For a few years he watched the marines and there rituals working with the chapters surfs when he became old enough to begin implantation (he was still only 9). Unlike most he knew what he was going to go through as he has watched new marines go through agonizing pain and he was ready to go through it. When the gene seed was implanted and the plague infected him he didn’t realize just how much pain he would go through he couldn’t sleep for a terran week until his body gave out and he passed out for 3 days straight when he woke up it seemed he had gained a small resistance to the pain which allowed him to train harder. As he grew the pain grew as it spread from his neck to the rest of his limbs fully covering his body except his face, his left hand, and his left leg finally after 9 long years of suffering he became a full battle brother and was allowed to augment his body his first augmentation was replacing his right arm with a new arm so he could use his dominant hand once again without pain that was his only augmentation until he became a sergeant when he was given an honorary mechanical implant that would soothe his internal pain which was great for him as he moved up the ranks he became more and more augmented but never touching the parts of him that were unaffected by the plague. Finally after becoming a lieutenant after a great battle. The trip to mars that he had waited for had come after he had missed 3 trips due to injuries or being in battle. As he loaded into the ship he saw much younger marines at that point he was 63 others were new battle brothers and a couple sergeants. The trip to the gauntlet was turbulent but they finally made it to it but when they entered a accident occurred a servitor fell into the ships generator causing their power to shut off for only a moment causing the geller field to fail for only a moment but in the split second a horde of demons streamed into the ship, at least a 100 crawled into the ship and started massecuring the marines in the ship. Most of them were inexperienced to chaos and were killed easily but a few more experienced marines were able to fight back Astovadion and and 10 other marines grouped together and began to fight back. Demon after demon they fought to defend injured and the crew. After a fight that seemed like a eternity the demons were killed and only 60 out of the 300 marines died on that ship. They sent out a smaller ship to return injured and dead and the uninjured continued to mars. When he arrived at mars he was amazed by it's red color. He arrived and that's where the records run short as mars training is not tracked in records all that's known is that he did well and unlike most stayed for a full 100 years. When he returned he was a different man he was cold and calculated unlike his original lighter personality. He stilled retained his motivation aspects but he only made accurate observations of their situation. This made people respect him more but he became a slightly ominous figure. At this point he was 163 years old and he was a tech lieutenant. After a month of being back he was surprised when his actions from 100 years ago made him a hero of the company and he was promoted to captain of the 4th company. His ceremony was grand and received the Blood laurels (there are only 9 of these and rumor states they are soaked in the blood of the first chapter master). After this he preformed many great deeds and eventually after the passing of the chapter master before him (teronek scanthor) he became the chapter master due to his certifications and awards. Currently he is still the Tech Chapter master and he is 487 years old as of the present
