Sibyl appears as a slim, angular human woman with the practiced stillness of someone who watches everything. Her human guise always wears a narrow smile and eyes that linger too long on handwriting. Her skin is smooth and pale like oiled parchment. Her fingers are long and ink-stained at the tips, the stains never fully washing away. When she moves she does so with small, precise steps like someone tracing letters. Unexpected detail: when she is deeply focused she unconsciously chews on the corner of a leather-bound ledger as if tasting the truth inside. In moments of anger small, almost invisible runic scars along her jaw shimmer, betraying her hag nature to those who look closely.
