Tinka nodded, "Oh sure, arcane mark?  I can cast that all day long.  Lets limit it to intersections and turns though, don't want to spend all day down here putting down marks."  She turned and muttering the words to the simple cantrip she touched her staff, which glowed with soft light to the wall next to the ladder they had just descended.  There was a bit of a glow on the wall and when her staff came away there sat at her eye level, a small sigil on the wall.  It was simple and looked as if it had been made with a bit of normal paint, though Velma was sure it would detect magically if one inspected it.  The mark itself was a simple letter "T" with an arrow pointing upwards, the direction they'd just come from.<br/><br/>"Now, as long as we don't miss these marks we should have no problem back tracking, which is good because this map doesn't go too far beyond the  area we're in now."  She unfurled the small map she carried and pointed, "These junctions here lead off north and south and are well documented, but these tunnels here aren't mapped yet, and might be a good place to start, yeah?"<br/><br/><br/><div class="spoiler_container"><div class="spoiler_header" onclick="hideSecond (this);" role="button">Spoiler: Click to Show/Hide</div><div class="spoiler_body">ooc - Tinka's staff has light cast on it and glows like a torch.  She can not see in low light so she needs it.</div></div>
