Valentis looked in wonder at the number of people picking up their arms to stop the hordes of oblivion, moments ago this small Imperial woman stated that she would attempt to close the gate, albeit in a rather demeaning manner, and upon hearing this claim from someone as young and small as herself, others took up the call.
The other man in the room who had a dog, the paladin, even the girl that looked unfit for any form of combat...
And yet, here he sat.

Valentis has lived a long life; he has no legacy barring perhaps being one of the most prominent Akaiviri scholars in the era, to die quietly, seemed unfitting.
Why, would he let these young people lay down their lives for the greater good without at least trying to do so himself, he may be old but with his age came considerable experience, knowledge and skill.
He was no stranger to combat and could fight better than most, Valentis would offer what little life he could to this cause, it may be a fools errand by the lot of them to walk into the depths of hell itself, but they could at least try.

With a bit of difficulty in his joints from being stationary for so long Valentis stood up, leaning slightly on his staff.
After straightening himself he walked over to the group by the doors; with Albert at his heel, - which inevitably lead to the chaos outside
Valen spoke out to them, his voice was soft and calm, but it held a stern undertone, one filled with conviction and confidence. 

"Excuse me, I am Valentis Fenotorai; I have been listening and watching to what you have all done and said - I must say, even in my old age, I cannot sit by and allow you all to march into the gates of hell alone - with what will my old bones have in them, consider them dedicated to the task at hand."
After noticing a few incredulous glances and looks towards him he continued.
"Don't let the looks of an old man fool you; I have braved the ancient and hostile lands of Akaivir and returned, what I have learned from those people has proven invaluable, I am a skilled warrior mage who can still give his all in a fight to the death.
Regardless of what you say, I am coming, on principle alone of nothing else."

Giving a slight nod to his companion followed by giving his head a ruffle he stated "Even my friend here can offer some assistance, he's quite the scout, his nose and ears are something that have warned me of a danger long before it comes into sight - in the unknown that is on the other side of that gate out there, surely all the help we can get will be needed."

Albert gave a happy bark to back Valen up on his points, it's been a long time since he had explored the unknown, and in his mind it was something that he originally started leaving that fortress for in the first place - turns out he got what he wanted.
If not the most extreme level of the unexpected.
