Lasch is beginning to show his years, but maintains a quiet strength born of study in the natural arts. His hair is a deep grey, tussled, and occasionally ponytailed, depending on the terrain. His simple robe conceals a chainshirt and quick draw shield when he travels. More than once a wandering cutpurse has learned the folly of a quick blade to the back. Lasch may not be a fighter, but his studies tell him to keep his shield slung high, near the neck to avoid a quick shot to the neck. He carries a short staff that he leans on as a cane, although he rarely actually requires it. Called "Cheatsheet," the staff has been intricately carved over the years with runes, letters and arcane writings. In a way, the staff is an extension of his memories; it is as much a part of Lasch's intellectual arsenal as his notes, quill, or tongue. A vest worn under his cloak is lined with tiny spikes that make grappling him a... painful experience. Lasch often jokes that this thwarts overzealous lovers from taking any liberties with him.
This joke usually falls flat with students.
His chain shirt fits snugly; he never needs to alter it since he keeps a strict regimen of stretching and light exercise each morning. The inside of the cloak is lined with pockets and hooks containing herbs, spices, papers, and small notebooks. People rarely notice the amount of items and equipment under the cloak, they assume the bulk is the product of years of study...not the preparations of someone that knows too much about the wider world.
Lasch usually wears running sandals, again meticulously tied in the style of a native people from far away.
Ultimately though, Lasch's defining feature is his eyes, deep midnight blue, almost black, they contrast almost startlingly with his pale skin. The same cutpurse that attempts a quick stab in the back has been met with these eyes, the same eyes that make students tremble with a fear, eyes they don't commonly associate with a professor. After that first failed blade, most don't try again. You see, nobody can tell Lasch that he doesn't understand. One look into his eyes and you know that he knows you.
