Tessia Eralith power up after Beast Will integration in The Beginning After the End

If you’ve been following The Beginning After the End long enough, you already know that Tessia Eralith is one of the most polarizing characters in the fandom. Some readers still cling to her early “princess in trouble” image—but honestly, that take is outdated.

After revisiting her full progression—especially the integration of the Elderwood Guardian’s Beast Will—it becomes pretty clear: Tessia is way stronger than she gets credit for. Not just narratively, but mechanically within the power system.

Let’s break it down like a proper fan deep-dive.

The Elderwood Guardian: A Blessing That Nearly Killed Her

Tessia’s power spike starts with the Elderwood Guardian Beast Will—an S-Class entity that most mages wouldn’t even survive touching.

Gifted by Arthur Leywin, this wasn’t just a power-up—it was basically throwing her into the deep end of elite-tier magic evolution.

But here’s the twist most casual readers miss: the Beast Will was corrupted.

That corruption (linked to the Vritra influence) caused:

• Mana backflow instability
• Internal conflict between Tessia and the will
• Near-fatal consequences during early assimilation

Instead of a clean buff, Tessia went through one of the roughest integrations in the series. This alone puts her above most “gifted” mages—because she didn’t just inherit power, she fought for control over it.

Integration Phase: Where Tessia Actually Becomes a Monster

Once she stabilizes thanks to the Asuran elixir, Tessia reaches the Integrate Phase—and this is where things get visually and mechanically insane.

What changes?

• Skin becomes pale, almost spirit-like
• Hair shifts to green, symbolizing full nature alignment
• Emerald aura wraps around her like a living armor

But this isn’t just aesthetic—it’s functional combat evolution.

Her combat toolkit in this state:

• Dual emerald blades formed from mana
• Large-scale root manipulation (battlefield control)
• Vines capable of restraining multiple enemies simultaneously
• Aura-based offense and defense hybrid

This is where she stops being “a strong mage” and starts feeling like a walking environmental hazard.

Power Scaling: Where Does Tessia Actually Rank?

Let’s be real—power scaling in TBATE gets messy fast. But Tessia’s position before the Legacy arc is pretty underrated.

Here’s a simplified breakdown:

She even defeats a retainer-level opponent (Bilal), and while people argue he was holding back, that doesn’t erase the feat.

Hot take: At her peak (pre-capture), Tessia was likely the strongest non-Lance mage alive.

The Cecilia Factor: Power Through Trauma

Now here’s where things get really interesting—and honestly, kind of underrated from a storytelling perspective.

When Cecilia takes over Tessia’s body, most people focus on the “power loss” aspect later.

But what actually happened is way more important:

• Tessia’s body endured extreme mana saturation
• Her consciousness survived inside the Beast Will space
• She even briefly reclaimed control during a critical moment

That’s not just resilience—that’s elite-tier mental strength.

After everything:

• She loses Cecilia’s Legacy abilities
• But keeps a refined, reinforced body
• And stabilizes at White Core level

So in a weird way, Tessia got a passive permanent buff from one of the most traumatic arcs in the series.

Why Her Beast Will Is Actually Unique

Let’s compare her to Arthur for a second.

Arthur’s bond gives him conceptual abilities like space-time manipulation.

Tessia, on the other hand, gets something completely different:

• Pure elemental amplification
• Direct synergy with her elven lineage
• Battlefield control through nature itself

She’s not breaking reality—she’s dominating the environment.

And that matters.

Because in large-scale war scenarios, Tessia is arguably more efficient than many Lances. She doesn’t just fight enemies—she controls the entire terrain.

What Makes Tessia So Underrated (and Why That’s Changing)

A lot of early criticism toward Tessia came from emotional decisions, dependence on Arthur in early arcs, and getting captured, which the story admittedly leans on.

But if you look at her full arc, the narrative tells a completely different story.

She survived a corrupted Beast Will, reached integration faster than expected, held her mind against Cecilia, and returned with a White Core and enhanced durability.

That’s not weakness—that’s top-tier progression.

Final Thoughts: Tessia’s Role Going Forward

Tessia isn’t trying to compete with Arthur’s Aether or Cecilia’s Legacy dominance, and she doesn’t need to.

She fills a completely different role: nature’s ultimate weapon.

With high mana efficiency, area control, and regeneration advantages in natural environments, she’s built for prolonged warfare.

And heading into future arcs, don’t be surprised if she becomes one of the most strategically important characters—not just in raw strength, but in overall impact on the battlefield.
