Hmm, I could always play him as a few years older -- simply because I envisioned the offensive and defensive spells to compliment one another, and to form (along with the healing spell) the core of the Bereaved's essential training. Some might be more inclined toward specializing in one specific branch from there, and so on. The final spell, as it were, is more of a passive effect, yes -- the actual invocation would be a sort of Deus Ex Machina that would in most normal circumstances involve the sacrifice of the caster himself.

The healing spell is not quite meditation -- more an ability that takes place while sleeping, when he has the capability to walk amongst the threads of his own dreams and those of others. Simply meditating would not be enough to reach this state, rather, you might see it more as a magical form of lucid dreaming.

As for a picture... Well, I'm bad with that. In fact, I tend to be a stickler for not finding portraits for my characters; imagery is evoked through artistry, and I very much enjoy moulding a character through words only, and allowing the reader to form their own impression as to appearances. If a picture is worth a thousand words, then how many pictures could I create with the same thousand words?
