baleful

Portending evil; ominous.

The street-lamps burn amid the baleful glooms, Amidst the soundless solitudes immense Of ranged mansions dark and still as tombs.

According to them all sorcerers, necromancers and evil-doers were born under the baleful influence of the seventh calendic sign[.]

Miserable, wretched, distressed, suffering.

Thou balefull Messenger, out of my sight:

round he throws his baleful eyes, that witnessed huge affliction and dismay […]

Deadly, mortal.

With balefull weedes, and precious Iuiced flowers, / The earth that's Natures mother, is her Tombe,

If some were akin to the Formori of the baleful fogs in Irish mythic history and the Mallt-y-nos, those she-demons of marshy lands immortalised by the Welsh bards, creatures huge and uncouth "with grey and glaring eyes," there were others who exceeded in beauty anything human.
