Sidra al-Najjar carries within her a jinn that furnishes her with wordless insight and warning. Its temper is a protective one, and most tender toward those in want: so it was when she gave up her cloak to Shehrazat, the young tiefling wasted by blood rot. Then Sidra's Djinn pressed upon her a sense of urgency touching the girl's condition — that though the illness might in time pass, it stood meanwhile in mortal peril of her life.
In the Undercity, Sidra set herself the errand of aiding Shehrazat, who had lain ill near a fortnight following an involuntary surge of her innate magic. She sought remedies of Papa Mert, an alchemist, and took part in the ritual by which a healing paste was laid upon the girl's afflicted places; throughout, she kept her mind wholly upon the giving of aid and comfort.
More lately Sidra has shown herself the dark-sighted member of her company. She cast a working to soften the party's tread, and examined a burlap bag upon a platform, where among the recovered bottles she made out two topical draughts against petrification. She offered baklava — a pastry of honey and nuts — to the local spirits, and enquired of the guards what manner of thing dwelt below. In one encounter she rounded upon a Bichura that had made to pick her pocket and slapped it away, then, begging its pardon, set baklava upon the boards, which thereupon lifted and vanished.
In a later mishap she fell into spiked water when a boardwalk gave way beneath her, and was hauled up again upon the far side by Gizem. She attempted Charm Person upon a nearby Merrow, which proved no lawful target, and then, more happily, laid the nearest Merrow low with Sleep; later she scorched a Medusa with sacred flame and healed her own hurts.
Beneath the Basilica Cistern and the Maiden Tower, the djinn's nature was altered altogether. When Sidra al-Najjar attuned to the Crown of Sargon in the thick of battle, a magical rebound tore the djinn bodily out of her — where it had dwelt as long as she could remember — and granted it a form of its own: a larger-than-life, kind-faced figure that named itself Faravi, "the imagined." Where once it had worn Sidra al-Najjar as a hermit-crab wears its shell, it now allowed that she held it as one holds a leash, professing a fondness grown over their years together and promising not to harm her — though it left her friends conspicuously unnamed, and warned that it might yet get up to mischief. Sidra al-Najjar became thereby a djinn-master warlock, able to yield her body to Faravi for a burst of power, whilst the djinn might take humanoid shape and act with a measure of its own will. Earlier, in the flooded prison, the djinn had counselled Sidra al-Najjar concerning The Shahmeran — known to it only by report, as one exceptionally adept in magic, though "there are always repercussions to her actions" — and the freed Shahmeran said the party might reach her again by asking the djinn.
