Imagine if they never made Solas a romance option, as originally planned.
I probably would never started to draw. And I wouldn't know who Dirthamen was.. the horror.
Speaking of which, I found another of his statues in front of a Tyrdda codex (Stanza: Thelm Gold-Handed, the Dreamer), and that image I thought was him and Ghilan'nain:

That Tyrdda codex was sounding suspiciously Dirthamen themed regarding Thelm Gold-Handed:
"Told his tribes a tale of treasure, over sea to north it gleamed,
Whispered words to drive the droves to golden city where he dreamed.
Counseled quick in dreams alone, Voices wiser man ignores,
Pushed the tribes until they screamed, Heed the dreams and cross the Waking."
"Fire flares as Thelm Gold-Handed, honey-tongued, repeats his lies.
"North to warmth, and golden cities, Whispers speak in Dreamers' ears!"
Silver scorched, the liar flies
On raven's beaks, to dream unwaking."
This reminds me of Dirthamen and Razikale, who also have lore about whispers, madness, ravens and honey:
"What of the old secrets that burn within our hearts?"
"Our Highest One, he deceives us.
The honeyed words that drip from his tongue
We know the despair they mask."
"The secrets are madness in our ears, but they are ours"
"And now Razikale is silent and madness descends."
"Razikale, O Shadow Which Obscures the Path Ahead, deliver your faithful, save us from the silence which devours."
"We will build a shrine to the Dragon of Mystery—implant foci into the walls, cut sacred designs into the stone, the better to hear her with. We will hear her voice again, or we will die."
The picture below is the beginning story of Andraste. But notice those ravens? They have faces. And see the eluvians in the background?

What if those things are servants of Razikale, and they hunted Dirthamen's secrets? Since Razikale (Dragon of mystery) is quite the equivalent to Dirthamen (Keeper of Secrets). Those in the Lost Temple of Dirthamen were worried about something coming after them once Dirthamen had been locked away:
They will come for us in the night
Those who could steal the words from our lips
