Hello readers!

If you look closely, this current Manwantara's ciranjivis like Parashuram, Kripa, Ashwathama,
they are actually going to be the saptarishis in the next Manwantara.

So, we can assume the ciranjivis of 11th Manwantara (which our story is unfolding in) are probably going to be
the saptarishis of 12th Manwantara.
And they are,

Tapaswí,
Sutapas,
Tapomúrtti,
Taporati,
Tapodhriti,
Tapodyuti,
and,
Tapodhan

So, these are the MahaGurus and avatars of different Supreme Gods in Dharma-Savarni Manu/ eleventh Manvantara.

The Saptarishis/ Maharishi/ Brahmarishis of 11th Manwantara will be,

Maharishi Niśchara,
Maharishi Agnitejas,
Maharishi Vapushmán,
Maharishi Vishńu,
Maharishi Áruni,
Maharishi Havishmán,
and,
Maharishi Anagha.

Just like we currently have Marici, Atri, Angira, Viswamitra, Vasishstha and other Rishis.

Now, I can't say for sure who is going to be what, can I? Because it's all going to be in the future. So, I made up my story based on the little info I gathered.

In this story, one of the saptarishis,
Maharishi Agnitejas was the guru of Rajkumar Jayaditya and Maharaj Jagadeesan.

And another Maharishi Vapushman was the father of Guru Pranacharya and grandfather of Viresh.

And,

Mahaguru Sutapas is kind of like Guru Parashuram here.

Mahaguru Sutapas

Backstory:

He is the most knowledgeable and skilled in weaponry among all the Gurus of eleventh Manvantara. Was taught by Supreme lord Shiva himself. He is also an incarnation of Narayan.

His body exerted heat unbearable because of severe austerity. The heat became too much and started creating havoc on earth and heaven itself. That's how he got the name Sutapas.

Mahaguru possess a hatred for Devtas. Because His wife Utapallavi was raped by Surya, the sun God. When he came to know about it, Guru Sutapas attacked Swarg and started killing all the Devtas. No Dev was able to fight him and most ran away in fear. Indradev, Suryadev, Vayudev, Chandradev and a few others went to Vaikunth to seek refuge. But Mahaguru chased them there too and beheaded Surya.

Later Prabhu Narayan calmed him and Suryadev was granted a new life as in absence of Surya, no life can survive on earth.

So, that's our Mahaguru whom even Gods are afraid of!

Even in fear of him Agni dev refused his wife's request of burning and purifying her.

(I adapted the story from the dynasty of Bharadvaja. Suryadev actually raped the second wife of a hermit. So, don't come bashing that I insulted Suryadev. It has happened already guys.)

Guru Tapodyuti will appear in the story to enlighten some people too.

Guru Tapodyuti

And please leave some comments!
I know this all may seem like a lot to take in, but I am trying to build it slowly and give you time to get familiar with everything.
Hope you enjoy!
