In Hinduism
Purana and Itihasa (epic history)
Source: archive.org: Shiva Purana - English TranslationAtidāruṇa (अतिदारुण) refers to “terrible”, according to the Śivapurāṇa 2.3.15 (“The penance and reign of Tārakāsura”).—Accordingly, as Brahmā narrated: “Then all those gods and sages consulted one another and in their great fright they came to my world and approached me in a piteous plight. [...] Coming to a definite conclusion with adequate thought as to the reason for the same, I went where the demon was performing penance in order to grant him the boon. O sage, I told him thus—‘Tell me what boon you want. A severe penance has been performed by you. There is nothing which cannot be granted to you’. On hearing these words of mine, Tāraka, the great demon, bowed and eulogised me and requested for a terrible [i.e., atidāruṇa] boon”.

The Purana (पुराण, purāṇas) refers to Sanskrit literature preserving ancient India’s vast cultural history, including historical legends, religious ceremonies, various arts and sciences. The eighteen mahapuranas total over 400,000 shlokas (metrical couplets) and date to at least several centuries BCE.
Shaktism (Shakta philosophy)

O best of the gods, I will explain. There is a great place, a mountain peak (called) Trikūṭa on the top of Meru. Agnituṅga arose there. He came into being without a sound. Powerful and surrounded by a garland of flames, he possessed the radiant energy of the twelve suns. The Person, unmanifest by nature, emerged from his navel. O Bhairava, he has no manifestation and is not perceived. And that is said to be the supreme place that is very frightening (atidāruṇa). [...]”.

Shakta (शाक्त, śākta) or Shaktism (śāktism) represents a tradition of Hinduism where the Goddess (Devi) is revered and worshipped. Shakta literature includes a range of scriptures, including various Agamas and Tantras, although its roots may be traced back to the Vedas.
In Buddhism
Mahayana (major branch of Buddhism)

They fell at the feet of the Bhagavān and said, “O Bhagavān, extremely dreadful (atidāruṇa) mantrapadas have been uttered. [...]’”.

Mahayana (महायान, mahāyāna) is a major branch of Buddhism focusing on the path of a Bodhisattva (spiritual aspirants/ enlightened beings). Extant literature is vast and primarely composed in the Sanskrit language. There are many sūtras of which some of the earliest are the various Prajñāpāramitā sūtras.
